Abstract :
Analysis suggests that very useful performance may be achieved in parametric amplifiers incorporating two varactor diodes. The most interesting configuration is a bandpass amplifier in which the varactors are the shunt capacitive elements, operated with a phase shift between diodes of 90° at the centre signal frequency and with the diodes mounted with opposite polarities. With inphase pumping this gives unilateral operation and a large potential bandwidth.
